This module deals with the fundamentals of distributed operating systems. It gives an understanding of the terminology, structures, functions, conceptions, key problems and implementation concepts of distributed operating systems.

Professional competence
The students:

• Evaluate the performance and functionality of distributed operating systems
• Are aware of the realisation problems of distributed operating systems
• Know and evaluate standard methods of solving problems in the context of distributed operating systems
• Use standard methods to solve problems in the context of distributed operating systems

Methodological competence
The students:

• Use standard methods of the distributed operating system domain to solve problems in other contexts
• Analyse and rank different solutions in the problem domain wrt. relevant properties

Social competence
The students:

• Solve problems in small teams
• Present their solutions to the members of the tutorial
• Duscuss their sdifferent solutions with members of the tutorial

Self competence
The students:

• Accept critcism
• Question their initial solutions in the light of newly learned methods
